What is not to love about a mid-engine hypercar concept? How about a three-pack of them?!

These concept Nissan models are pretty amazing. All Nissans?

Not exactly. The two Dome Zeroes below were from a startup by the same name, but were powered by the Nissan straight-six engine from the Z-cars of the era, making 145-horsepower in these applications.

Limited any-res photos of each are readily available, but the Nissan Heritage collection does offer the specs of the 1987 MID4 Type II -- which predates the Acura NSX and also foreshadowed the 300ZX and later, the 240Z of the 1990s.
